Marines found 32 homemade bombs containing a total of 130 kilos of explosives in a rural area outside Tumaco, a port city on Colombia’s Pacific coast, the navy said Sunday.

“The 32 homemade devices were found inside a hideout and contained the explosive” pentolite, the navy said.

Marines found 68 meters (222 feet) of detonating cord and 200 meters (655 feet) of duplex cable, “which were apparently going to be used to build the mechanism for activating the devices,” at the site in Palo Seco, the navy said.

The bombs were found thanks to assistance from a “network of informants” before “the materiel could be used by the enemies of peace to perpetrate attacks against the civilian population and the security forces during the year-end period,” the Pacific Naval Force said.

No fighting or arrests were reported in connection with the seizure of the bombs, whose owners were not identified.

Both the Revolutionary Armed Forces of Colombia, or FARC, the country’s oldest and largest leftist guerrilla group, and gangs that work for drug traffickers operate in the area.

Nearly two tons of explosives have been seized by naval personnel since the beginning of the year, the navy said.
